A dunam or dönüm, dunum, donum, dynym, dulum is a non-SI unit of area used in the Ottoman Empire and still used, in various standardized versions, in many countries formerly part of the Ottoman Empire. It was defined as "forty standard paces in length and breadth",[1] but varied considerably from place to place.
History[]
The name dönüm, from the Ottoman Turkish دونمك / dönmek (to turn) appears to be a calque of the Byzantine stremma and had the same size. It was likely adopted by the Ottomans from the Byzantines in Mysia-Bithynia.[2] In Arabic, the word is spelled دونم (dūnam) which is "a square measure (Iraq = about 2500 m²; Israel = roughly, 1000 m²)."[3]
Definition
Bulgaria
In Bulgaria it is called dekar (декар) and is equal to 1,000 square meters.[]
Cyprus
In Northern Cyprus the donum is Şablon:Convert/sqft. In the Republic of Cyprus older Greek Cypriots also still refer to the donum, although this is gradually being replaced by another local Greek Cypriot dialect word, σκάλες (ska′les), rather than the mainland Greek word stremma. However, officially Cyprus uses the square metre.[]
Iraq
In Iraq, the dunam is Şablon:Convert/m2.[citation needed][]
=== Israel, Syria, Palestinian territories, Jordan, Lebanon and Turkey ===
In Israel, Jordan, Lebanon, the Palestinian territories, Syria, and Turkey the dunam is Şablon:Convert/m2. Before the end of the Ottoman Empire and during the early years of the British Mandate of Palestine, the size of a dönüm was Şablon:Convert/m2, but in 1928 the metric dunam of Şablon:Convert/m2 was adopted, and this is still used.[4]
=== Serbia ===
In Serbia, the unit is called dunum (дунум) but sometimes it's mistakenly called dulum (дулум) by some folks. It is equal to 1,000 square meters[5]
Variations[]
Other countries using a dunam of some size include Libya, Syria, Albania, and the countries of the former Yugoslavia.[citation needed]
The Greek stremma has the same size as the metric dunam.[citation needed]
The metric dunam is particularly useful in hydrological calculations as 1 dunam times 1 mm (a unit commonly used for measuring precipitation) equals exactly one cubic meter.
